The perimeter of a fence is 64 feet. The length is 4 feet less than twice the width. What is the length of the fence?

givi [52]

Answer:

20 feet

Step-by-step explanation:

let the width be x

length = 2x-4

perimeter = 2 length + 2 width = 2(2x-4)+2x = 4x-8+2x = 6x-8

6x-8 = 64

6x = 72

x = 12

length = 2x-4 = 2(12)-4 = 20

A farmer's land is separated into sections of size 3 3/4 acres. Suppose there are 2 1/5 such sections. How many acres of land do

Nadusha1986 [10]

Answer:

This is simple multiplication of fractions, not too bad!

we have 2 7/9 sections of farmland, each 2 1/5 acres large. To find the total acreage, multiply 2 1/5 by 2 7/9. The first step here is to convert to improper fractions.

To convert to improper fractions, multiply the denominator of the mixed number by the "whole number" portion of it. Then, add the numerator of the mixed number. For example, for 2 1/5, I would multiply 5 * 2 to get 10, then add 1 to get 11. Then, I keep the original denominator, so 11/5.

Let's do the same for 2 7/9. 9 * 2 = 18, then add 7 to get 25. The improper fraction is 25/9.

Now, we multiply the two fractions. This is just multiplying both numerators and both denominators, straight across.

(11*25)/(9*5) = 275/45 => 55/9, so that's the total acreage, or in decimal form, about 6.11 acres.

RQPO is a trapezoid. What is the value of x?<br><br> 2<br><br> 63°<br><br> (6x + 9°<br><br> R

scZoUnD [109]

Answer:

18°

Step-by-step explanation:

Find the diagram attached

From the diagram, since the opposite side are parallel, the sum of the adjacent angle is 180 degrees

From the diagram, m<RQP + m<QPO = 180

Given

m<RQP = 6x+9

m<QPO = 63

Substitute

6x+9+63 = 180

6x + 72 = 180

6x = 180 - 72

6x = 108

x = 108/6

x = 18 degrees

Hence the value of x is 18°
